Hi,
We have a problem with Reply-To field...We receive some messages from external customers who have modified his Reply-To field to reply to another mail account.
Example:
From:customer1@customer.com
Reply-To: customer2@customer.com
The problem is when a user of my domain reply one of this messages. The recipient address must be reply-to account (customer2), but the mail is sended to From account (customer1.
This scenario only occurs in SWA access. If I use Outlook or Thunderbird, the mail is sended to the correct address (the reply-to). This is because is the mail client who read the header and compose the Recipient address
